Mini Digital Programmable DC Auto Range Power supply Laboratory Automation Component Testing
Mini Auto Range DC Power Supply 40V 20A Switching Adjustable Lab Regulated
Constant Power & Wide Range Utility: Engineered with advanced 300W auto-ranging capabilities, delivering flexible voltage and current profiles. One single unit effectively replaces multiple traditional fixed-range power supplies to optimize workbench space and lower equipment costs.
Pre-Settable Voltage & Current Parameters: Operators can dynamically pre-set precision output voltage and current parameters while the output state is safely turned off, mitigating accidental power spikes or live-connection loads.
Dedicated Hardware Keypad Lock: A simple long-press activates a centralized console safety lock, freezing the tuning interface to eliminate human tuning variance, stray contact, or parameter shifting during long-duration automated testing sequences.
Dual OVP/OCP Protection Mechanisms: Independent, easily configurable protection circuits with visual alert indicators that automatically arrest active power delivery when target thresholds are crossed, safely outputting alert logs directly to the console.
Flexible Group Profile Recall (M1-M3): Built-in non-volatile storage presets save up to 3 discrete setup profiles. Users can instantly recall pre-mapped electrical tests via the faceplate, accelerating production turn times and structural diagnostic loops.
Independent Output Termination Panel: Designed with an isolated hardware ON/OFF output rocker completely distinct from the master rear switch. This enables rapid, wear-free signal gating while continuously preserving active device settings.
